There has been no core. This theory is just nonsense. Last season, there was no late season collapse. There was just mediocrity with points being gradually dropped until GVB left. The league was gone very early due to Celtic’s form. Godson had nothing to do with this, so only 2 players can even be remotely linked to us failing last season. The season before, there was a mid-season collapse. Lundstram only played 27 mins of the three key games in this collapse that put Celtic top. Later in that season we lost pace with Celtic with Lundstram having to play centre back in one of those games. Again, only 2 players can be remotely linked to this mid-season collapse and it's not even the same two as the other season. To go back to 19/20 is just ludicrous. Completely different team. And our mid-season collapse happens while Tavernier is injured, and similar to this season, when he returns from injury we just can't turn it around. Yet again, only 1 of the “old guard” can be linked to the collapse and yet again, it isn't even the same one. This is ignoring the huge failings of the attacking players in those seasons. Quite simply, Celtic were better and we weren't good enough.
In conclusion, people need to stop peddling simplistic, reactionary nonsense.
